charles28 117 Report post Posted October 9, 2015 Hi Guys, I'm having an odd problem. I can have my heater set on cold for both driver and passenger sides and intermittently I get hot air coming out of the drivers side vents. (happens about 3/5 times when I use the car now). It doesn't do it every time, if I have the A/C on the air is cold out of all the vents, however I usually just have it turned off with just the fan running bringing cooler air in from outside. I thought heater valve, but if it was this, would it be intermittent ? Quote Share this post Link to post Share on other sites
